Description

  The present invention relates to a formwork panel having a structure in which a flat plate is integrally joined to a corrugated panel, and a concrete formwork in which a pier is attached to the panel.

Currently, there are several concrete molds used for construction of buildings and the like depending on the materials used.
The most widely used concrete formwork is one using a panel (plywood, plywood). In the case of constructing concrete exposed walls, a panel coat with paint applied to the surface of the panel or a curved veneer is used where a curved surface is required in order to make the surface of the finish smooth.
However, in the concrete formwork using the control panel, when the concrete is placed, the sash is raised from the control panel and sticks to the concrete. May cause problems in the strength of the concrete.
In addition, the concrete formwork using the panel is soaked in the panel that the oil-based release agent is applied to facilitate the peeling from the concrete, and the harmful substances released from the adhesive used to make the panel. Has a negative impact on the human body, and there is a problem in disposal after use, such as dioxin emission problems at the time of disposal. Even if it is brought into an industrial waste treatment facility, the treatment may be refused because it contains the aforementioned harmful substances.
Furthermore, when using a concrete formwork that uses a panel at a construction site, etc., it is necessary to use the above-mentioned panel, panel coat, and curved veneer properly depending on the construction site. In some cases, it is necessary to prepare all these types in advance. And it takes time and effort.

  Formwork panels using plastic plates have also been devised, but because they use plastics, they are vulnerable to fire, they must be treated at the time of recycling, cost is high, and on-site curved surface construction is not possible Disadvantages have been pointed out.

A concrete form using a steel plate panel has been devised and used as a concrete form that solves such problems.
In concrete casting using concrete formwork using steel plate panels, after the concrete is cured or hardened, the installed formwork plate is often buried as it is, and the work period can be shortened because there is no need for removal work. And there is a merit that it does not need to be disposed of. However, since the steel plate is used, it is very heavy, and there is a disadvantage that labor is required for the work for installing the mold. Moreover, the fact that it cannot be used again is one of the factors that increase the construction costs.

Patent documents 1 and patent documents 2 are publicly known as a concrete formwork using a steel plate panel.
In Patent Document 1, a trench sheet bent into a tooth shape is loosely accommodated between both edges of a face plate provided with an edge on the back surface, and several stoppers used for joining the sheet vertically and horizontally are disclosed. A steel plate flexible mold apparatus having metal fittings and fastening bars is described. However, in this formwork apparatus, there are many parts that are complicated and require processing and welding of parts at the time of creation, which is troublesome.
Patent Document 2 discloses a concrete formwork composed of a corrugated panel, which is a formwork for a concrete wall, in which a flat inner surface plate having a runner for receiving the lower end of the panel and a cap for receiving the upper end of the formwork panel is joined. An invention is disclosed in which an interior panel is attached to an outer surface of a frame panel to cover and hide the formwork panel. However, in this invention, since the reuse of the formwork panel is not taken into consideration, as described above, the cost for construction is increased. Moreover, it is necessary to pulverize the concrete when the building is demolished. However, according to the present invention, it is necessary to separate the formwork panel embedded in the construction from the concrete, which is troublesome and expensive. .
